(1 point) A steel ball weighing 128 pounds is suspended from a spring. This stretches the spring feet. The ball is started in motion from the equilibrium position with a downward velocity of 3 feet per second. The air resistance (in pounds) of the moving ball numerically equals 4 times its velocity (in feet per second). Suppose that after t seconds the ball is y feet below its rest position. Find y in terms of t. (Note that this means...

Problem 1. (point) A steel ball weighing 128 pounds is suspended from a spring. This stretches the spring feet. The ball is started in motion from the equilibrium position with a downward velocity of 9 feet per second. The air resistance (in pounds) of the moving ball numerically equals 4 times its velocity on feet per second). Suppose that after t seconds the ball is y feet below its rest position. Find y in terms of t. (Note that this...
PLEASE ANSWER BOTH PROBLEM SETS PLEASE ANSWER BOTH (1 point) A steel ball weighing 128 pounds is suspended from a spring. This stretches the spring 528 feet. The ball is started in motion from the equilibrium position with a downward velocity of 7 feet per second. The air resistance (in pounds) of the moving ball numerically equals 4 times its velocity (in feet per second). Suppose that after t seconds the ball is y feet below its rest position. Find...
A hollow steel ball weighing 24 pounds is suspended from a spring. This stretches the spring 4 inches. The ball is started in motion from a point 3 inches above theequilibrium position.Let u(t) be the displacement of the mass from equilibrium. Suppose that after t seconds the ball is u feet below its rest position. Find u (in feet) in terms of t.(Note that the positive direction is down.)Take as the gravitational acceleration 32 feet per second per second.
